Of the heresies, some receive their appellation from a [person’s] name, as that which is called after Valentinus, and that after Marcion, and that after Basilides, although they boast of adducing the opinion of Matthew [without truth]; for as the teaching, so also the tradition of the apostles was one. Some take their designation from a place, as the Peratici; some from a nation, as the [heresy] of the Phrygians; some from an action, as that of the Encratites; and some from peculiar dogmas, as that of the Docetæ, and that of the Hæmatites; and some from suppositions, and from individuals they have honoured, as those called Cainists, and the Ophians; and some from nefarious practices and enormities, as those of the Simonians called Entychites.
